Function Documentation

void jack_shutdown

(

arg

)

JACK calls this shutdown_callback if the server ever shuts down or decides to disconnect the client.

int process	(	jack_nframes_t	nframes,
		void *	arg
	)

The process callback for this JACK application is called in a special realtime thread once for each audio cycle.

This client follows a simple rule: when the JACK transport is running, copy the input port to the output. When it stops, exit.
